A major security flaw has been found in laptops and desktops by Dell
A major security flaw has been found in laptops and desktops by Dell that could have allowed cyber attackers to gain access to the systems. The cybersecurity research team by Sentinel Labs, which spotted the vulnerability, says that millions of Dell laptops and desktops are at risk due to this.
The team says that the flaw could have led to a range of cyber attacks, including a complete system takeover by the hackers. The vulnerability was found in the form of a bug in a preinstalled software in Dell laptops and desktops.
As per a report on the vulnerability, the bug could have allowed hackers to get admin-level access to a PC. Once hackers gain this access, they could possibly have installed malware deep inside the system so as to lock a user out of his own machine.
The bug was found in the Dell BIOS Utility driver, called DBUtil. A module inside the DBUtil driver is responsible for delivering BIOS updates on Dell laptops and desktops. The security team reported five flaws with the module in the report.
Two of these are memory corruption glitches, two are input validation failures and one logic flaw. Collectively, these flaws could be exploited by hackers for attacking and taking over a target system.
The findings were reported to Dell on December 1 last year. Since then, Dell has released a security update to its customers to address this vulnerability so make sure your computer is always updated.
